EXAM 2: MECHANICAL VENTILATION NCLEX QUESTIONS AND ANSWERS 2025

EXAM 2: MECHANICAL VENTILATION NCLEX QUESTIONS AND ANSWERS 2025 The purpose of adding PEEP to positive pressure ventilation is to a. increase functional residual capacity and improve oxygenation b. increase FIO2 in an attempt to wean the patient and avoid O2 toxicity c. determine if the patient is in synchrony with the ventilator or needs to be paralyzed d. determine is the patient is able to be weaned and avoid the risk of pneumomediastinum - Answer a The nursing management of a patient with an artificial airway includes a. maintaining the ET tube cuff pressure at 30 cm H20 b. routine suctioning of the tube at least every 2 hours c. observing for cardiac dysrhythmias during suctioning d. preventing tube dislodgment by limiting mouth care to lubrication of the lips - Answer c The nurses monitors the patient with positive pressure mechanical ventilation for a. paralytic ileus because pressure on the abdominal contents affects bowel motility b. diuresis and sodium depletion because of increased release of atrial natriuretic peptide c. signs of cardiovascular insufficiency because pressure in the chest impedes venous return d. respiratory acidosis in a patient with COPD because of alveolar hyperventilation and increased PaO2 levels - Answer c A comatose patient with a possible cervical spine injury is intubated with a nasal ET tube. The nurse recognizes that what is a disadvantage of a nasal ET tube in comparison with an oral ET tube? a. requires the placement of a bite block b. is more likely to cause laryngeal edema c. requires greater respiratory effort in breathing d. requires the placement of an additional airway to keep the trachea open - Answer c In preparing a patient in the ICU for oral ET intubation, what should the nurse do that is most important for successful intubation? a. place the patient supine with the head extended and the neck flexed b. tell the patient that the tongue must be extruded while the tube is inserted c. position the patient supine with the head hanging over the edge of the bed to align the mouth and trachea
